Poor Quality Granite Installation - HELP!

I'm in the process of having a house built by a local home developer. Everything with the process has been wonderful until the granite was installed in my kitchen. I picked the granite from a small sample size in the builder's design center. The granite that was installed has prominent orange rust rings in various spots of the counters. In some areas, the grain of the granite has these rusty spots and circles that truly look like something has been spilled on the counters. I am very dissatisfied with the look of the counters and have asked the builder to replace. I feel the counters were used with a slab of granite that lent itself to poor aesthetic. The builder is telling me that this is quite common in granite and that they cannot guarantee that the next piece of granite won't be the same or worse. Prior to building with them, I visited many of their model homes in my community and never saw any granite as bad as this granite. In fact, they were all pristine. I feel like the granite is unacceptable. I don't think these marks are something that anyone with a design eye would use in a home.

Can someone please look at my pictures and advise if you feel the same?

I am also enclosing a pic of the sample granite that is paired with my kitchen cabinets when I chose the granite to be installed.

Well, that is ugly, but appears to be a natural part of the stone. Best bet is to approve the material before cutting/installing. If that is even an option with your builder or the supplier. If not, get a credit and buy it yourself.

When we had our granite installed we went through several slabs that had that exact staining. The color was Ouro Brasil/New Venetian which is basically the same thing as you have. Its natural rust spots within the granite. But not very appealing to the eyes! I would tell them to replace it or let you pic the slab yourself!

NC,
I do a lot of kitchen remodels, most of the tops are granite. I always send the customer to the granite fabricators yard and let them pick out their own slabs. In some cases where the granite has a lot of movement (i.e. wild grain patterns), the fabricator will have the customer return and approve the placement of the templates on the slabs before any cutting is done.
